The computation is shown below

Given that

Paul required to buy 5 by 8 pound of peanuts

And, the scale at the store is in sixteenths

So, the measure that should be equivalent is

Here the denominator should be 16 so it should be multiplied by 2

= 5 ÷ 8 × 2 ÷ 2

Answer:

Therefore

15.

25c^{2}-9

16.

(y+8)(y+1)

17.

(x-3y)(x-7y)

Step-by-step explanation:

15.

(5c^{2} +3)(5c^{2}-3)

Using the Identity (a + b)(a - b) = (a² - b²) we get

Consider here a = 5c and b = 3 then we will have

((5c)^{2} -(3)^{2})=25c^{2}-9    .....as required

16.

y^{2}+9y+8

Here Factorize 8 such that sum up to be 9

∴ 8 × 1  = 8 and 8 + 1 =9

y^{2}+9y+8\\y^{2}+8y+y+8\\y(y+8)+1(y+8)\\(y+8)(y+1) ... as required

17.

x^{2}-10xy+21y^{2}

Here Factorize 21 such that sum up to be -10

∴ -3 × -7  = + 21 and -3 - 7 = - 10

x^{2}-10xy+21y^{2}\\x^{2}-3xy-7xy+21y^{2}\\x(x-3y)-7y(x-3y)\\(x-3y)(x-7y) ........as required

Therefore

15.

25c^{2}-9

16.

(y+8)(y+1)

17.

(x-3y)(x-7y)

Which is a possible equation of a parabola that intersects the x-axis at points (-1,0) and (3,0)? Question 2 options: y=x2+3x−3
olga2289 [7]

Answer:

Step-by-step explanation:

Where a graph intersects the x-axis is where the solutions or zeros of the quadratic are found...where y = 0.

If the points of intersection are x = -1 and x = 3, then putting those into factors gives us (x + 1)(x - 3) = 0.  FOIL that out to get the quadratic.

x^2-3x+x-3 which simplifies to

x^2-2x-3=y

Looks like the third option there.
